Travel support structure

ABSTRACT

A support structure for at least partially supporting a user&#39;s head is described. The support structure comprises a frame having a head engaging portion and a shoulder engaging portion, the shoulder engaging portion adapted to spread the load of the user&#39;s head over a user&#39;s shoulder, the frame being shaped to the contour of the user&#39;s body from the head engaging portion to the shoulder engaging portion.

FIELD OF THE INVENTION

The present invention relates to a support structure for at least partially supporting a user's head when travelling. Particularly, the support structure is to at least partially support a user's head when sleeping whilst sitting in a relatively upright position.

BACKGROUND TO THE INVENTION

The use of travel pillows is common practice for passengers in cars, planes, buses and trains. There are four main types of travel pillow, currently on the market: memory foam pillows, polystyrene bead filled pillows, air filled pillows and feather or stuffing filled pillows.

These pillows come in various forms, but generally fall into one of three categories: C-shaped, O-shaped, or L shaped.

The pillows currently on the market are generally aesthetically unpleasant and have further drawbacks. For example, the U-shaped pillows generally do not support a user's head at the front below the chin, or at the sides, which causes the chin to fall forward and the neck to lie at an awkward angle, the O-shaped pillows do not cater for a wide enough range of different neck sizes the air filled pillows can be difficult to inflate and to plug shut and the stuffed pillows are so poor they don't even provide any support. The bead-filled pillows are better, as they can be quite firm, but also lack support in the upright position at the front of the neck. Furthermore, the conventional neck pillows can move in use, particularly away from the desired area of contact with the user, to be less supportive.

SUMMARY OF THE INVENTION

According to a first aspect of the present invention there is provided a support structure for at least partially supporting a user's head, the support structure comprising:

a frame having a head engaging portion and a shoulder engaging portion, the shoulder engaging portion adapted to spread the load of the user's head over a user's shoulder, the frame being shaped to the contour of the user's body from the head engaging portion to the shoulder engaging portion.

DETAILED DESCRIPTION OF THE DRAWINGS

Referring firstly to FIG. 1, a perspective view of a support structure, generally indicated by reference numeral 10 for at least partially supporting a user's head (not shown) according to a first embodiment of the present invention.

The support structure 10 comprises a frame 12 and an anchoring means 14 in the form of a scarf 16. The frame 12 is contained within a pocket 18 located at a first end 20 of the scarf 16.

The frame 12 will now be described in more detail with reference to FIGS. 2, 3, 4 and 5, perspective, top, side and then views of the support structure frame 12 of FIG. 1.

The frame 12 comprises a single piece of resilient polymeric material and defines a head engaging portion 30 and a shoulder engaging portion 40. As will be shown, the shoulder engaging portion 40 is adapted to spread the load of the user's head over a user's shoulder. The frame 12 is shaped to the contour of the user's body from the head engaging portion 30 the shoulder engaging portion 40.

The head engaging portion 30 comprises a first head engaging limb 32 and a second head engaging limb 34, the first and second head engaging limbs 32, 34, being connected by a head engaging portion connecting member 36.

The shoulder engaging portion 40 comprises a first shoulder engaging limb 42 and a second shoulder engaging limb 44, the first and second shoulder engaging limbs 42, 44 being connected by a shoulder engaging portion connecting member 46.

The head engaging portion limbs 32, 34 have respective head engaging surfaces 52, 54 which are angled towards each other to cup, in use, a part of user's jaw. Similarly, the shoulder engaging portion limbs 42, 44 have respective shoulder engaging surfaces 62, 64 which also angled towards each other to cup between them two portions of the convex surface of a user's shoulder when in use.

It will be noted, the limbs 32, 34, 42, 44 are paddle shaped in that they are wider at their free ends, 56, 58, 66, 68 than at their connecting ends 57, 59, 67, 69 where they join their respective connecting members 36, 46

In the embodiment shown in FIG. 2-FIG. 5, the frame 12 is in an uncompressed configuration. That is, the configuration shown on these Figures is a “not in use” configuration, the frame 12 being adapted to be compressed under the weight of the user's head. In this uncompressed configuration, the head engaging portion connecting member 36 and the shoulder engaging portion connecting member 46 are in contact at their respective midpoint's 38, 48. This will be discussed further in due course

In use, the frame 12 is fitted into the pocket 18 of the scarf 16. Referring to FIG. 1, the sides of the pocket 80, 82 maintain a substantially constant spacing between the head engaging portion limbs 32, 34 and a substantially constant spacing between the shoulder engaging portion limbs 42, 44. The scarf surface 84 providing a bridging means 86 to provide a comfortable contact surface for the user.

Operation of the support structure 10 will now be described with reference to FIG. 6 comprising FIGS. 6A-6D, a sequential series showing fitting of the support structure 10 to a user 100.

The user 100 places the first end of the scarf 20 containing the frame 12 inside the scarf pocket 18 against their neck 102 such that the frame head engaging portion 30 rests against the underside of the user's jaw 104 and the frame shoulder engaging portion 40 lies across the user's shoulder 106.

The user 100 takes a scarf second end 108 and passes it around their neck 102, until the scarf encircles their neck 102.

The scarf first and second ends 20,108 are provided with hook and loop fastener portions 110, 112 which are brought together to secure the support structure to the user 100, thereby providing structure 10 adapted to at least partially support the user's head 114 permitting them to sleep comfortably in an upright position.

Referring to FIG. 7, a close-up of the frame 10 shown in FIG. 6B in which the frame 12 is partially compressed, it will be noted that the head engaging portion connecting member 36 and a shoulder engaging portion connecting member 46 for much of the length of the respective portions. This provides extra rigidity to the support structure 10, allowing for an initial “give” when the user 100 puts the weight of their head 114 on the support structure 10 by providing more resistance as the user applied weight increases and the size of the contact area between the connecting members 36, 46 increases.

Various modifications and improvements may be made to the above described embodiments without departing from the scope of the present invention. For example, the bridging means may include an elasticated strap between the free ends of the limbs.
